Abstract: A high-speed printer includes a prerecorded multicharacter font stored in holographic form. Selection of a stored character for projection onto a recording medium is accomplished by means of a conventional X-Y acousto-optic deflection system. To achieve justified lines and attractively composed words, the printer must have a variable character- and word-spacing capability. This capability is realized by combining an electro-optic light deflector with the acousto-optic system in such a way as to controllably vary the angle at which an incident light beam interrogates a selected holographic character. For each different interrogation angle, the selected character is projected to a slightly different location along a row of the recording medium. In this way there is provided a vernier adjustment of the positions of characters to be printed.
